Abstract

The invention discloses an energy-absorbing bumper. According to the energy-absorbing bumper, energy-absorbing elements and a telescoping mechanism are mounted between a front bumper beam and a rear bumper beam; each added energy-absorbing element comprises a damper and a spring to commonly enhance the energy-absorbing effect; the telescoping mechanism which can be shrunk elastically and uniformly is adopted to disperse collision energy on various damping and energy-absorbing elements so as to be uniformly absorbed by the bumper, nonuniform energy absorbing caused by centralized collision points is prevented, the buffering effect of the bumper is fully improved, and the energy-absorbing effect of the bumper is exerted to the maximal extent. Therefore, by adopting the novel bumper which can absorb collision energy in a telescoping manner, the effects of buffering and energy-absorbing of the bumper can be realized, and excessive impact caused by the rigid connection of the conventional bumper and a vehicle body is effectively avoided, so that collision energy transferred to the vehicle body and the human body is reduced, and the function of protecting the vehicle and passengers is realized.

Description

Energy absorbing bumper
Technical field
The invention belongs to auto-safety mechanism field, particularly relate to a kind of energy absorbing bumper.
Background technology
Bumper/spoiler belongs to automotive safety auxiliary device, is installed on before and after vehicle body.When colliding, bumper/spoiler can protect vehicle body, avoids vehicle body to suffer direct collision.For low speed collision, it can be played a protective role by dispersing impact forces; For the shock of speed, its energy-absorbing effect is limited, and protective effect also has limitation.Existing bumper/spoiler is mainly rigidly attached on chassis, and when colliding, himself can absorb certain energy, and quite a few is then delivered on vehicle body, thus causes vehicle body to damage and personal casualty.Although some bumper/spoiler also has energy-absorbing function, cause limited efficiency because energy-absorbing is unbalanced.
Summary of the invention
The technical problem to be solved in the present invention is to provide simple, the respond well energy absorbing bumper of a kind of structure.
For solving the problems of the technologies described above, the present invention by the following technical solutions: energy absorbing bumper, comprises bumper front crossbeam and bumper back beam, is provided with power-absorbing and telescoping mechanism between bumper front crossbeam and bumper back beam; Power-absorbing comprises bumper and spring, and bumper two ends are arranged on bumper front crossbeam and bumper back beam respectively, and spring housing is outside bumper; Telescoping mechanism is by fork-shaped telescopic boom to forming, and each fork-shaped telescopic boom is connected to form by connecting pin by two expansion links, and expansion link two ends are connected in the slotted eye on bumper front crossbeam and bumper back beam with bolt respectively.
Bumper has two, is arranged on respectively outside about bumper/spoiler.
Fork-shaped telescopic boom, to there being two, is arranged between two bumpers.
Federal bumper for existing structure protects not enough problem to vehicle body, and contriver has designed and produced a kind of energy absorbing bumper, is provided with power-absorbing and telescoping mechanism between its bumper front crossbeam and bumper back beam.The power-absorbing increased comprises bumper and spring, and they can strengthen energy-absorbing effect jointly; Can then make collision energy to be distributed on each damping power-absorbing thus the thick stick equilibrium that is insured absorbs by the telescoping mechanism that shrinks of uniform elastic, prevent because the concentrated energy absorbing caused of collision point of action is uneven, the buffer action of abundant raising bumper/spoiler, has played the energy-absorbing function of bumper/spoiler to greatest extent.Therefore; the Novel bumper of the scalable absorption collision energy of application the present invention; the effect of bumper/spoiler buffering energy-absorbing can be reached; the impact that causes of being rigidly connected that effectively prevent traditional insurance thick stick and vehicle body is excessive; thus reduce the collision energy be delivered on vehicle body and the person, play the effect of protection automobile and occupant.
Accompanying drawing explanation
Fig. 1 is the structural representation of energy absorbing bumper of the present invention.
In figure: 1 bumper front crossbeam, 2 bolts, 3 expansion links, 4 springs, 5 connecting pins, 6 bumper back beams, 7 bumpers.
Detailed description of the invention
As shown in Figure 1, energy absorbing bumper of the present invention comprises bumper front crossbeam 1 and bumper back beam 6, is provided with power-absorbing and telescoping mechanism between bumper front crossbeam and bumper back beam; Power-absorbing comprises bumper 7 and spring 4, two bumpers are arranged on outside about bumper/spoiler respectively, and each bumper two ends are arranged on bumper front crossbeam and bumper back beam respectively, and spring housing is outside bumper; Telescoping mechanism by fork-shaped telescopic boom to forming, two fork-shaped telescopic booms are to being arranged between two bumpers, each fork-shaped telescopic boom is connected to form by connecting pin 5 by two expansion links 3, expansion link two ends are connected in the slotted eye on bumper front crossbeam and bumper back beam with bolt 2 respectively, and can slide in slotted eye along with the flexible of expansion link.
Bumper/spoiler of the present invention is installed on front portion or the afterbody of automobile, for when colliding by spring buffer collision impact, by absorber collision energy, uniform shrinkage before and after telescoping mechanism assurance thick stick, to disperse collision impact.When bumper/spoiler collides, under the effect of telescoping mechanism, bumper/spoiler to after contraction, spring occur compression simultaneously bumper also shrink, thus play shock absorbing and absorb the effect of collision energy.
